Bug Description

Log function detect OSX system language and OpenGL version incorrectly
By default, Stellarium should display in the language that system is using....But on OSX, Stellarium cannot detect the system language.
The OpenGL version supported by my macbook air mid-2012 should be up to 4.1, but stellarium display it as 2.1
